Methods

any(bool test(AppStatus element)) Future<bool>
Checks whether test accepts any element provided by this stream.
inherited
asBroadcastStream({void onListen(StreamSubscription<AppStatus> subscription)?, void onCancel(StreamSubscription<AppStatus> subscription)?}) Stream<AppStatus>
Returns a multi-subscription stream that produces the same events as this.
inherited
asyncExpand<E>(Stream<E>? convert(AppStatus event)) Stream<E>
Transforms each element into a sequence of asynchronous events.
inherited
asyncMap<E>(FutureOr<E> convert(AppStatus event)) Stream<E>
Creates a new stream with each data event of this stream asynchronously mapped to a new event.
inherited
cast<R>() Stream<R>
Adapt this stream to be a Stream<R>.
inherited
contains(Object? needle) Future<bool>
Returns whether needle occurs in the elements provided by this stream.
inherited
didChangeAccessibilityFeatures() → void
Called when the system changes the set of currently active accessibility features.
inherited
didChangeAppLifecycleState(AppLifecycleState state) → void
Called when the system puts the app in the background or returns the app to the foreground.
override
didChangeLocales(List<Locale>? locales) → void
Called when the system tells the app that the user's locale has changed. For example, if the user changes the system language settings.
inherited
didChangeMetrics() → void
Called when the application's dimensions change. For example, when a phone is rotated.
inherited
didChangePlatformBrightness() → void
Called when the platform brightness changes.
inherited
didChangeTextScaleFactor() → void
Called when the platform's text scale factor changes.
inherited
didHaveMemoryPressure() → void
Called when the system is running low on memory.
inherited
didPopRoute() Future<bool>
Called when the system tells the app to pop the current route, such as after a system back button press or back gesture.
inherited
didPushRoute(String route) Future<bool>
Called when the host tells the application to push a new route onto the navigator.
inherited
didPushRouteInformation(RouteInformation routeInformation) Future<bool>
Called when the host tells the application to push a new RouteInformation and a restoration state onto the router.
inherited
didRequestAppExit() Future<AppExitResponse>
Called when a request is received from the system to exit the application.
inherited
distinct([bool equals(AppStatus previous, AppStatus next)?]) Stream<AppStatus>
Skips data events if they are equal to the previous data event.
inherited
drain<E>([E? futureValue]) Future<E>
Discards all data on this stream, but signals when it is done or an error occurred.
inherited
elementAt(int index) Future<AppStatus>
Returns the value of the indexth data event of this stream.
inherited
every(bool test(AppStatus element)) Future<bool>
Checks whether test accepts all elements provided by this stream.
inherited
expand<S>(Iterable<S> convert(AppStatus element)) Stream<S>

inherited
handleCancelBackGesture() → void

inherited
handleCommitBackGesture() → void
Called when a predictive back gesture is finished successfully, indicating that the current route should be popped.
inherited
handleError(Function onError, {bool test(dynamic error)?}) Stream<AppStatus>
Creates a wrapper Stream that intercepts some errors from this stream.
inherited
handleStartBackGesture(PredictiveBackEvent backEvent) bool
Called at the start of a predictive back gesture.
inherited
handleUpdateBackGestureProgress(PredictiveBackEvent backEvent) → void

override
map<S>(S convert(AppStatus event)) Stream<S>
